Title: Cleaning of semiconductor wafer
Inventor: WASHITANI AKIHIRO
IPC: H01L21/304
Filed: 1989-09-06
Abstract: PURPOSE:To surely remove a fine particle and a residual chemical liquid which have adhered to a trench hole by a method wherein a gas or a medium solution whose boiling point is lower than that of a cleaning liquid is added, a pressure inside a tank is pressurized within a specific range, the gas or the medium solution ls dissolved in the cleaning liquid and the pressure inside the tank is reduced. CONSTITUTION:In a state that a wafer 1 is immersed in a cleaning liquid 5, a gas or a medium solution whose boiling point is lower than that of the cleaning liquid 5 is added from the outside of a cleaning tank; the inside of the cleaning tank 11 is pressurized within a range of 1 to 10kg/cm<2>. The gas or the medium solution is dissolved sufficiently inside the cleaning liquid 5; after that, a pressure inside the cleaning tank 11 is reduced within a range of 1 to 10kg/cm<2> to 200 to 1 to 200 Torr. As a result, molecules of the gas or the medium solution which has been dissolved in the cleaning liquid 5 at the inside and the outside of a trench hole 9 are expanded by a pressure difference and are moved upward as air bubbles 21. Conse quently, the cleaning liquid 5 inside the trench hole 9 is moved actively to the outside of the trench hole 9; at the same time, the cleaning liquid 5 outside the trench hole 9 seeps into the trench hole 9 by a volume portion of the air bubbles 21 expelled to the outside of the trench hole 9; a so-called convection current is generated. Thereby, it is possible to expel a fine particle and a residual chemical liquid which have adhered to the trench hole 9 to the outside of the trench hole.

Title: Coding device
Inventor: SATO YOSHIO
IPC: H03M3/04
Filed: 1986-09-30
Abstract: PURPOSE:To omit a memory of large capacity that serves as a code book by using an artificial noise generator in place of the code book as a generating means for coded residual signals. CONSTITUTION:The sound signal supplied through an input terminal undergoes a linear estimation analysis through a linear estimation analyzer 8. Then a residual signal series is produced by a linear estimating instrument 2. A noise generator 7 produces an artificial noise series by using a code supplied from a code generator 4 as the initial value and gives the noise series to a distance scale calculating means 3. The means 3 calculates the distance scale between the residual signal series supplied from the instrument 2 and the artificial noise series supplied from the generator 7 and outputs this scale to the generator 4. The generator 4 outputs a code having the minimum distance scale calculated by the means 3 to a multiplexing device 5 as a code against a residual signal among those codes outputted to the generator 7. The device 5 multiplexes said code and a coefficient of estimation given from the analyzer 8 and outputs them.
